datAshur Personal2 8 GB - Secure Flash Drive - Password Protected - Portable - Military Grade Hardware Encryption.

Never go wrong with the datAshur brand. This is the only usb product that is whitelisted in my company. Needed it in a hurry and I wasn't disappointed. Works amazingly well, value for money and the speed in which it saves and retrieves data is matched. The size is cute and there is hardly any heat issues, definitely one to recognise as the best product around.

Brilliant! Despite some reviews claiming that it was difficult, if not impossible, to change the built-in security code to one user-chosen, I ordered this rather expensive flash drive and I was not disappointed. It really does what it claims to do; the code system is great, I was able to change it to my chosen character-and-numbers code (on my second attempt, it is true, but then I had failed to follow the instructions correctly the first time) and it is working beautifully ever since. I have been using it for almost a month now; it never fails to load, inserting the security code is as simple as in a hotel-room safe, for instance, and it feels really secure. I always carry with me, on a USB pen, an image of my credit cards, personal ID, driver's license and other important documents, in case the originals are lost or stolen, and I used to worry with the possibility of losing that pen and thus exposing my private data to anyone who would find it. This iStorage pen really solved my problem. It is an expensive gadget (and, unfortunately, I did pay for it the full price, therefore my review is not influenced by any offer or discount made by the manufacturer...), but I feel it is worth every penny.

Ideal for my requirements and easy to use

The Datashur is a recently released USB drive from iStorage. It comes in three storage sizes: 4, 8 and 16GB. Similar in concept to the USB hard drives from iStorage, these USB drives offer hardware encryption fully authenticated by a user-defined PIN which is entered directly via keys on the unit itself. In order to accommodate PIN entry, the device includes a rechargeable battery, which is charged automatically when inserted into a USB port. The unit is small enough to sit alongside other devices plugged into adjacent USB ports but, in order to accommodate the need for a keypad, the device is longer that most other USB drives. I would certainly recommend using a short USB male/female cable to plug the device into your PC, just to ensure no damage is caused to it or your PC when in use. The other advantage of using a cable is that it allows PIN entry on the unit when the drive is already plugged into your PC. Operation of the device is simplicity itself, though a little fiddly due to the necessarily compact size of the keypad. Keypad entry is reliable but the keys are small and have only a small amount of travel and would be difficult for someone with dexterity problems. The keys have clear legends and the inclusion of alphanumerics on the keypad (similar to a phone keypad) means you can use a more easily remembered alphanumeric PIN (rather than hard to remember numeric-only PINs on competing devices). The keys legends appear to be quite durable and unlikely to wear with use (a problem encountered by a few similar products). Until you enter a PIN onto the device your computer will not recognise it as a disk drive, so your valuable data is completely protected. When you unplug the device or the USB port ceases to provide power, the unit will automatically lock and PIN re-entry will be required in order for the drive to become visible again. The PIN has to be 7-15 characters in length, giving billions of possible combinations. If an incorrect PIN is entered 10 times in succession, the encryption key and your disk contents are deleted - making it impervious to brute force attacks! Entry of a PIN onto the unit itself completely ensures your valuable PIN cannot be captured by any malware on your computer; it also means that the device requires no authentication software, making it platform independent. During PIN creation and PIN entry, two status lights guide you and give acknowledgement of wrong or correct PIN entry. A third (rather bright) blue light shows when data is being transmitted from/to the drive. Once entered, the PIN makes the disk's single partition entirely visible to the Host PC. So, paranoid users may want to use additional measures in order to protect individual files when connecting the drive to unknown host. One thing I would like to have seen on this drive is some degree of plausible deniability in the encryption system. For systems with on-board PIN authentication this could be achieved by the use of a second partition that is only visible upon entry of a second PIN. The Datashur drive works with a Windows PC, Mac, Linux or any other system that has a USB port that can recognise USB drives formatted to FAT32 - even printers and embedded systems! You can, of course, format the drive to NTFS or other format available on your system, but at the expense of platform independence, so FAT32 is really recommended for most users. On first insertion into a Windows PC, the necessary drivers are automatically downloaded from Microsoft update - this took just a matter of seconds for me; I am not sure what happens on other systems. No software is included with the unit because it does not need any. A full user manual is included on the drive and there is also a credit card-size durable instruction sheet to carry in your wallet. The unit looks physically robust, though no claims are made as to its ability to withstand crushing or temperature extremes but the Datashur does have a certificate for water resistance. One thing I do like is the very secure metal cable for attaching to a keyring etc - unlike the flimsy 'string' seen on some competing products. Inside, the unit is physically protected from hackers by encasing everything in epoxy resin Should anyone attempt to open the unit then breaking open the epoxy resin should destroy the unit, so that your valuable data cannot be extracted by use of a microscope! When not in use, the entire unit is protected by a sturdy aluminium case. The encryption used is top-notch military-grade AES 256 bit. The encryption key is not held in memory but in hashed form on the built-in cryptographic chip. This makes the encryption key virtually impervious to discovery or accidental deletion. It is simply not necessary to retain a copy of the encryption key on any other device (a weakness suffered by software-based systems). The user can generate a new encryption key at any time but this will wipe the drive's contents - so be sure to backup first. Again, unlike some competing drives, a new encryption key can be generated on-the-fly any number of times; other, presumably less secure devices, have a limited number of encryption keys built-n during manufacture. iStorage have applied for FIS 140-2 Level 3 certification for this product and expect to achieve this in March 2012. This is really the US Government's gold standard that encrypted drive manufacturers strive for. I think you can fully expect a 10-20% price rise when this occurs, so buy your Datashur encrypted USB drive now!

I like this a lot but like others I found setting a code virtually impossible to begin with - and it was only a review from another purchaser that solved the problem for me. Once done, everything seemed so simple and the drive works very effectively and does indeed provide absolute security. Perhaps the instructions need rewriting? The small physical size is a real bonus and I haven't found a drive of comparable size and portability offering such a high level of security. I have been using this producer’s larger drives for some years and they have been very fine, with a high level of encryption and integrity of contents, although their casing does seem to experience some deterioration, for reasons that aren’t clear. All in all, the smaller version is expensive, but worth it for the peace of mind.

This is an amazing little device. It's very simple to use and setup. You have to make sure you follow the steps correctly. Once you've entered the correct PIN 1,1,2,2,3,3,4,4 you then enter your PIN. I find this device very secure for anybody wishing to hold personal sensitive files. With it having an inbuilt keyboard you basically prevent anybody from accessing it without the key. It also resets and wipes memory after 10 failed attempts which means there is absolutely no way somebody can guess your correct PIN in 10 attempts, making is secure against BRUTE FORCE ATTACKS. Ultimately worth it for anybody worried about security.

I have used this product for nearly 3 years now, it works great and I have yet to have a single issue with it. I would highly recommend to anyone. Definitely worth the money. The only concern I had and I'll share it, is the inconvenience of the size, because it is difficult to fit and keep on my keys so I just put it in my pocket instead.

This is my second set of two. I have all my important info on them and carry one to keep my data in case something happens to the house while I am gone, stuff does happen. Anyway, I somehow lost one of the original ones and was bummed out. But I am hoping that it works well as I had a large passcode. I did wind up changing all my passwords which I should have done previously. In any case, I like the Datashur's security and got new ones and updated my passcode longer. It is a twitch test to change the passcode as others have noted. After 6 attempts, I got it, LOL! Another thing, in hindsight, is sometimes even if you put in the right code, it doesn't always turn on. I think that is another good thing if someone is trying the million permutations to get into it.

It is a nice-looking USB with robust security features. Since I just got it the time will tell how good this truly is. So far so good!

Value for money. Easy to use. Satisfactory security.

After experiencing some issues, managed to get resolved, and has been a great purchase. Would recommend the product!

Sehr gut und alles funktioniert wie erwartet. Ich freue mich sehr das es so ein tolles Produkt mit diesen Eigenschaften gibt.
